Tsunami risk appears to pass for U.S. after massive Russian earthquake; South American countries issue new warnings
The 8.8 magnitude temblor struck off the coast of the Kamchatka Peninsula, an isolated strip along the Pacific Ocean, overnight. Residents of the peninsula fled inland as 16-foot waves caused flooding.
Immediately after the earthquake, Hawaii issued a tsunami warning and evacuation orders, but by Wednesday morning, the warning was downgraded to an advisory and evacuation orders were lifted on the Big Island and Oahu. Japan's Meteorological Agency also lowered its alerts to advisories.
States on the U.S. West Coast were placed under a tsunami advisory that remained in effect Wednesday morning.
But U.S. Secretary of Homeland Security Kristi Noem said the worst was over.
"We were fully deployed and ready to respond if necessary but grateful that we didn't have to deal with the situation that this could have been," she told reporters in Chile, where she is meeting officials.
Experts had warned earlier that the effects of the earthquake may continue through Wednesday.
"A tsunami is not just one wave," said Dan Snider, the tsunami warning coordinator with the National Tsunami Warning Center in Alaska. "It's a series of powerful waves over a long period of time. Tsunamis cross the ocean at hundreds of miles an hour — as fast as a jet airplane — in deep water. But when they get close to the shore, they slow down and start to pile up. And that's where that inundation problem becomes a little bit more possible there."
"In this case, because of the Earth basically sending out these huge ripples of water across the ocean, they're going to be moving back and forth for quite a while," which is why some communities may feel effects longer, he said.
The Pacific Tsunami Warning Center, which lifted the Hawaii warning, had forecast that the estimated arrival time of the first tsunami waves there would be 7:17 p.m. Tuesday local time (1:17 a.m. Wednesday ET). Officials urged people to move inland and shelters were opened in many parts of Hawaii. Hawaii Gov. Josh Green said that Black Hawk helicopters had been activated and high-water vehicles were on standby in case authorities needed to conduct rescue operations.
So far no damage has been recorded, but it will take two to three hours of observation before authorities will be able to determine whether the event has passed, Green said.
Green said data from Midway Atoll, a small island between Japan and Hawaii, measured waves that were about 6 feet from peak to trough. He warned that waves hitting Hawaii could be bigger or smaller.
Cars jammed streets and highways in Honolulu, even in areas away from the shore, as people tried to evacuate. Jimmy Markowski, who was visiting Honolulu's Waikiki Beach, said that the roads on the island were packed.
"We decided to go to elevated ground," Markowski told "CBS Mornings." "We passed a few other gas stations, you couldn't even get in 'em."
CBS Honolulu affiliate KGMB-TV reported that the first waves coming ashore were relatively small, though they came at high tide. Flooding was reported in numerous shoreline areas, including parking lots and boat harbors.
The PTSC said the Hilo, Hawaii, gauge recorded a tsunami height of 4.9 feet relative to normal sea levels and the Kahului, Maui, gauge recorded a tsunami height of 4 feet.
At around 10 p.m. local time, Pacific Tsunami Warning Center director Chip McCreery said wave heights appeared to have peaked.
The Oregon Department of Emergency Management said on Facebook at around 3 a.m. local time that small tsunami waves were expected along the coast and urged people to stay away from beaches, harbors and marinas and to remain in a safe location away from the coast until the advisory is lifted.
"This is not a major tsunami, but dangerous currents and strong waves may pose a risk to those near the water," the department said.
A tsunami warning was posted for a portion of the California coast near the border with Oregon, but was later lowered to an advisory. California Gov. Gavin Newsom posted a statement on X saying the state's Office of Emergency Services was coordinating with local officials in Northern California, from Cape Mendocino to the Oregon border.
The advisory extended along the whole California coast.
Dr. Lucy Jones told CBS News Los Angeles that experts with the National Oceanic and Atmospheric Administration were predicting waves of about a foot for most of Southern California.
The National Weather Service said on X that tsunami waves arrived in Monterey around 12:48 a.m. PT. Other cities along the California coast reported small to moderate-sized tsunami waves. A video shared by the National Weather Service Bay Area showed boats bobbing up and down in a harbor as they were rocked by small tsunami waves.
The National Weather Service in Eureka, California, said around 4 a.m. local time that Crescent City had seen tsunami waves of about 3.5 feet, with activity building as the region approached a minor high tide. High tide could lead to more flooding. Crescent City has seen dozens of tsunamis since the 1930s, including a 1964 event that killed 11 people and destroyed hundreds of buildings.
The National Weather Service Bay Area warned that even if the waves are small, they can cause "seriously dangerous" currents. The first waves also may not be the highest, the agency said, warning people to avoid coastal areas until told it's safe.
On Alaska's Aleutian Islands, officials recorded waves up to 1.4 feet above tide levels.
The quake was centered about 74 miles east-southeast of the Russian city of Petropavlovsk-Kamchatsky, which has a population of 180,000. Multiple aftershocks as strong as 6.9 magnitude followed and experts predict aftershocks of up to 7.5 for at least a month, according to the Russian News agency TASS.
The temblor appeared to be the strongest anywhere in the world since the 9.0 magnitude earthquake off northeastern Japan in March 2011 that caused a massive tsunami that set off meltdowns at a nuclear power plant. Only a few stronger earthquakes have ever been measured around the world.
Earlier this month, five powerful quakes — the largest with a magnitude of 7.4 — struck in the sea near Kamchatka. The largest was at a depth of 12.4 miles and was 89 miles east of the city of Petropavlovsk-Kamchatsky.
The Kremlin said regional authorities on Kamchatka were well prepared for the quake. Kremlin spokesman Dmitry Peskov noted that the warnings were issued timely and people were quickly evacuated from dangerous areas. He added that the buildings proved resilient to shocks.
A video released by a Russian media outlet showed a team of doctors at a cancer clinic on Kamchatka holding a patient and clutching medical equipment as the quake rocked an operating room, before continuing with surgery after the shaking stopped. Officials said the doctors will receive decorations.
Tsunami heights of about 9 to 13 feet were recorded in Kamchatka. Severokurilsk Mayor Alexander Ovsyannikov said the port in the city was flooded by tsunami waves, washing fishing boats into the sea. He said no major damage was recorded. Authorities on the Kamchatka peninsula lifted the tsunami warning for the area, some 11 hours after the quake hit. Russian authorities said several people were injured, without giving a figure. The risk of aftershocks and waves remains, officials said.
On Wednesday, lava began to flow from Klyuchevskaya Sopka, the largest active volcano in the northern hemisphere. The 15,584-foot volcano, located in the east of Kamchatka, last erupted in 2023. Observers heard explosions and saw streams of lava on the volcano's western slopes, the Kamchatka branch of the Russian Academy of Sciences' geophysical service said.
Scientists have anticipated an eruption, with the volcano's crater filling with lava for several weeks and the mountain spitting out plumes of ash.
"The Klyuchevskoy is erupting right now," the Russian Geophysical Survey said on Telegram, posting photos of an orange blaze on top of the volcano and adding that "red-hot lava is observed flowing down the western slope. There is a powerful glow above the volcano and explosions."
Sometimes described as the "land of fire and ice," Kamchatka is one of the most active volcanic regions in the world. It has about 300 volcanoes, of which 29 are active, according to NASA Earth Observatory.
The quake had a preliminary magnitude of 8.0, Japanese and U.S. seismologists said. The U.S. Geological Survey later updated its strength to 8.8 magnitude and a depth of 13 miles.
People went to evacuation centers in affected areas of Japan, with memories fresh of the 2011 earthquake and tsunami that caused reactor meltdowns at a nuclear power plant. The tsunami alert disrupted transportation, with ferries, trains and airports in the affected area suspending or delaying some operations.
Waves of about 2 feet were recorded on Japan's northern island of Hokkaido, and at least one person was injured.
Japan's Fire and Disaster Management Agency said nearly 2 million residents are now under evacuation advisories in more than 220 municipalities along the Pacific coast as of midday Wednesday. Japan's Chief Cabinet Secretary Yoshimasa Hayashi said waves could remain high for at least one day, and he urged evacuees to take precautions and stay well hydrated in the summer heat. He told evacuees they might not be able to return home by the end of the day on Wednesday.
No abnormalities in operations at Japan's nuclear plants were reported on Wednesday. The operator of the Fukushima Daiichi plant, heavily damaged by the 2011 tsunami, said about 4,000 workers are taking shelter on higher ground at the plant complex while monitoring remotely to ensure safety.
China's Ministry of Natural Resources' Tsunami Warning Center issued an alert for parts of the country's east coast along Shanghai and Zhejiang provinces. The warning forecasted that waves could reach between one to three feet. The provinces are already under an alert as Typhoon CoMay is expected to land in the Zhejiang province on Wednesday.
Some tiny and low-lying Pacific island chains are among the world's most imperiled by tsunamis and rising seas due to climate change. People were urged to stay away from coastlines until any wave surges passed late Wednesday in Fiji, Samoa, Tonga, Federated States of Micronesia and Solomon Islands. Philippine authorities advised people to stay away from the beach and coastal areas.
"It may not be the largest of waves, but these can continue for hours and expose people swimming in the waters to danger," Teresito Bacolcol of the Philippine Institute of Volcanology and Seismology told The Associated Press.
Elsewhere, a tsunami of under a foot was forecast to hit parts of Vancouver Island, British Columbia. Mexico's navy warned that tsunami waves will start reaching the northern coast in Ensenada, near California, at around 02:22 a.m. Wednesday local time, and waves could progress along the Pacific coast to Chiapas state, around 07:15 a.m. local time.
In Chile, tsunami warnings were upgraded to their highest level on Wednesday morning. The alert covers most of the nation's 4,000-mile Pacific coastline. The country's Education Ministry also canceled classes along much of the coast.
New Zealand authorities warned of "strong and unusual currents and unpredictable surges" along all coastlines of the South Pacific island nation. The emergency management agency said people should move out of the water, off beaches and away from harbors, marinas, rivers and estuaries.
There are four levels of tsunami alerts: warning, advisory, watch and information statement, according to the National Weather Service.
A tsunami warning is the most severe. It means residents should take action due to a coming tsunami that may cause widespread flooding.
A tsunami advisory means there's the potential for "strong currents or waves dangerous to those in or very near the water," according to the NWS.
A tsunami watch advises those to be prepared because a distant earthquake has occurred and a tsunami is possible.
The lowest level of alert is a tsunami information statement from the NWS, which advises people to "relax" since an earthquake has occurred, but there is no threat or it was very far away.

Japan braces for more heat after hottest July on record
People in Japanexperienced their hottest July on record this year, with officials warning of "severe heat" to hit northern and western regions of the country in August. Average temperature in July was 2.89 degree Celsius higher than the 1991-2020 average for the same month, the nation's Meteorological agency said on Friday. On July 30, Japan experienced its highest recorded temperature — 41.2C in the western region of Hyogo. Early end to rainy season For three years in a row, July has brought record-breaking heat to Japan, with the average monthly temperature reaching new heights in 2023, 2024, and now in 2025. This July is the warmest since the Japan Meteorological Agency began recording data in 1898. The amount of rainfall to hit Japan's northern and western regions in July was lower than average. Moreover, the rainy season ended three weeks earlier than usual in western Japan, creating another unwanted record. Heat affecting cherry blossoms On Friday, the agency predicted more rainy and cloudy days in the first half of August, but said more sunny days are expected later this month, "Please pay attention to temperature forecasts and heatstroke warning alerts, and take appropriate measures to prevent heatstroke. In areas with less precipitation, please be careful to manage your water," the agency's press release warned. The average temperature for the June to August quarter is "likely to require the record, too," Yoshinori Oikawa, head of the weather agency's Center for Information on Climate Extremes said, as reported by Japan Times. Experts have warned that Japan's famous cherry trees are bloomer earlier than usual or not blooming completely due to this shift in weather. The winters are not long or cold enough to trigger flowering. Edited by: Darko Janjevic

The Latest: Tsunami warnings lifted in many places but Chile raises it to highest level
A tsunami sent waves into parts of Russia, Japan, Hawaii and the U.S. West Coast after an 8.8 magnitude earthquake struck off the Russian Far East early Wednesday. The quake was one of the biggest ever recorded. Several people were injured, but none gravely. No major damage has been reported. The danger appeared to be subsiding in some places. But Chile upgraded its warning to the highest level for most of its lengthy Pacific coast, and New Zealand has said tsunami activist has begun to reach its shores, about 6,000 miles (9,656 kilometers) from the quake's epicenter. Here's the latest: New Zealand says tsunami activity has begun Emergency management officials say coastlines of New Zealand are experiencing strong currents and wave surges as tsunami activity reaches shores. It's early morning Thursday in New Zealand. An alert broadcast to every cell phone says the threat is likely to remain in place until at least midday. Evacuations haven't been ordered. But people throughout the South Pacific island nation are warned to stay out of the water and away from beaches, shorelines, harbors, rivers and estuaries. New Zealand is about 6000 miles (9,656 kilometers) from the quake's epicenter. Officials warn that the first tsunami waves might not be the largest to arrive and people should treat the threat as real until the alert is canceled. Tsunami advisory is canceled for Oregon, Washington state The tsunami advisory is canceled for Oregon and Washington state. Experts say it's challenging to know exactly when all of the tsunami alerts and advisories will be dropped. 'It's kind of hard to predict because this is such an impactful event and has created so many of these waves passing by. It's hard to say exactly when they're going to be done,' said Dave Snider, tsunami warning coordinator for the National Tsunami Warning Center in Alaska. Snider said tsunami advisories are still in effect for Hawaii, parts of Alaska and parts of California. In Alaska, 'we didn't feel a thing' A spokesperson for Alaska's state emergency management agency, Jeremy Zidek, says in a text that no damage has been reported. The community of Adak recorded the largest tsunami wave in Alaska at 2.7 feet, or less than a meter. 'I think what really surprised us, given the magnitude of that earthquake on Kamchatka, is that we didn't feel a thing,' Adak City Manager Breck Craig said. 'The bad thing is, that it might be our turn next.' Colombia orders evacuation of beaches Officials in Colombia have ordered the complete closure and evacuation of beaches and low-tide areas along the country's Pacific coast. Maritime traffic is also being restricted. Officials say strong currents and tsunami waves were possible in two coastal states, including one that borders Ecuador. Threat to US 'has passed completely' U.S. Secretary of Homeland Security Kristi Noem said the threat of a major tsunami hitting the United States 'has passed completely.' Noem, speaking in Chile where she is attending meetings with officials, told reporters in the capital, Santiago: 'We're in really good shape right now. We were fully deployed and ready to respond if necessary, but grateful that we didn't have to deal with the situation that this could have been.' Chile raises tsunami warning to highest level Chile has upgraded its tsunami warning to its highest level. The red alert covers most of its 6,400-kilometer (4,000-mile) Pacific coastline, from Arica and Parinacota near its northern border to Magallanes in the far south. The Education Ministry also canceled classes along much of the coast. Explosions and lava flows on Russian volcano Lava has begun to flow from the largest active volcano in the northern hemisphere Wednesday following the earthquake off Russia's far eastern coast. The Klyuchevskaya Sopka — which last erupted in 2023 — stands at 4,750 meters (15,584 feet) in the east of Russia's Kamchatka region. Observers heard explosions and saw streams of lava on the volcano's western slopes, the Kamchatka branch of the Russian Academy of Sciences' geophysical service said. Scientists have anticipated an eruption, with the volcano's crater filling with lava for several weeks and the mountain spitting out plumes of ash. Sometimes described as the 'land of fire and ice,' Kamchatka is one of the most active volcanic regions in the world. It has about 300 volcanoes, of which 29 are active, according to NASA Earth Observatory. California city urges people to stay away from beaches Officials warned people to stay away from beaches and waterways in Crescent City, California, which has observed dozens of tsunamis since the 1930s, including one that killed 11 people and destroyed hundreds of buildings in the city in 1964. The warning came after a 8.8 magnitude earthquake struck off Russia's Far East coast on Wednesday. The U.S. National Weather Service's Eureka office reported tsunami waves with a maximum height of 3.6 feet (1.1 meters) in Crescent City — enough to create minor coastal flooding and inundation. The 1964 event, considered the worst tsunami disaster recorded in the United States, began with a 9.2 magnitude earthquake in Alaska, according to the Crescent City website. Three smaller waves caused little damage, but then a big wave — nearly 21 feet (more than 6 meters) — devastated 29 city blocks and killed 11. The city's downtown was mostly rebuilt and today a walking tour highlights high-water marks posted on surviving buildings, objects pushed by waves and memorials to those who died. Japan downgrades last tsunami alert Japan has downgraded its last remaining tsunami alert, which was in the country's north. Tsunami advisories remain in place for its Pacific coast following the 8.8 magnitude earthquake that struck off Russia's Far East on Wednesday. Russian authorities cancel tsunami warnings for 2 regions Russian authorities on the Kamchatka Peninsula and Kuril Islands have canceled their tsunami warnings but say the risk of aftershocks and waves remains. The regional branch of Russia's Emergency Ministry on Kamchatka warned that scientists expect aftershocks at magnitudes of up to 7.5. It said that more tsunamis are possible in the Avacha Bay where the regional capital of Petropavlovsk-Kamchatsky is located. Russia says regional authorities were prepared The Kremlin said that regional authorities on Kamchatka were well prepared for the quake. Kremlin spokesman Dmitry Peskov noted that the warnings were issued timely and people were quickly evacuated from dangerous areas. He added that the buildings proved resilient to shocks. Tsunami-driven tides build in northern California Tsunami activity continued to build in northern California as high tide approached Wednesday morning with maximum confirmed heights along the coast of 3.6 feet (1.1 meters) in Crescent City, 3.0 feet (.9 meters) in Arena Cove and 1.2 feet (.4 meters) in Humboldt Bay, according to the National Weather Service office in Eureka. The measurements in Crescent City and Arena Cove were high enough to create minor coastal flooding and inundation, the weather service said on social media, adding that tsunami activity will persist and people should avoid beaches and harbors. Crescent City officials warned on social media that higher surges could arrive around high tide and could affect lower lying areas. They asked people to stay away from beaches and waterways. Hawaii and parts of Japan downgrade tsunami warnings Hawaii and parts of Japan downgraded tsunami warnings, with Hawaii lifting evacuation orders across the state while leaving a tsunami advisory in place. Officials in Hawaii said residents who had evacuated could return to their homes. Maj. Gen. Stephen Logan, the Adjutant General of the State of Hawaii Department of Defense, said an advisory means there is the potential for strong currents and dangerous waves, as well as flooding on beaches or in harbors. Russia declares state of emergency in areas hit by earthquake The Russian authorities declared a state of emergency on the Kuril Islands and in Petropavlovsk-Kamchatsky, the main city on the Kamchatka peninsula. They earlier reported that several tsunami waves flooded the fishing port of Severo-Kurilsk, the main city on the islands, and cut power supplies to the area. Russia's Oceanography Institute said tsunami waves that hit the city topped 6 meters (19 feet). Japan asserts territorial rights to the four Pacific islands it calls the Northern Territories. They were taken by the Soviet Union in the final days of World War II, and the dispute has kept the countries from signing a peace treaty. 8.8-magnitude quake was among the strongest this century Wednesday's 8.8-magnitude quake was among the four strongest earthquakes this century, and among the eight strongest since 1900, according to the USGS. The earthquake occurred along the Pacific Ring of Fire, the ring of seismic faults around the Pacific Ocean where most of the world's earthquakes occur. The 2011 Japan quake and the 2004 earthquake off Indonesia were 9.1 magnitude, and a 2010 earthquake in Chile also was recorded at 8.8 magnitude. Japanese official warns evacuees they might not be able to return home by day's end Japan's Chief Cabinet Secretary Yoshimasa Hayashi told evacuees in the tsunami-affected areas that they might not be able to return home by the end of the day on Wednesday. Hayashi said waves could remain high for at least one day, and he urged evacuees to take precautions and stay well hydrated in the summer heat. Damage and minor injuries reported in Russian Far East Local authorities on Russia's Kamchatka peninsula said several people were injured during the massive quake, but didn't give an exact number. Oleg Melnikov, head of the regional health department, said a few people hurt themselves while rushing to leave buildings and a hospital patient received an injury while jumping out of a window. Melnikov said that all injured people were in satisfactory condition. A video released by Russian media outlet showed a team of doctors at a cancer clinic on Kamchatka holding a patient and clutching medical equipment as the quake rocked an operating room, before continuing with surgery after the shaking stopped. Officials said the doctors will receive decorations. In Petropavlovsk-Kamchatsky, Kamchatka's regional capital, the quake damaged a local kindergarten, which was not in operation due to ongoing repair work. Water recedes at Hawaii beaches as tsunami reaches Oahu Hawaii Gov. Josh Green said officials observed water receding by 20 to 30 feet (6 to 9 meters) at Haleiwa Harbor on Oahu, the state's most populous island, an indication tsunami waves will arrive. The waves pulling out left boats to lay on dry rock and sand. 'That gave us pause,' Green said. So far no damage has been recorded, but it will take two to three hours of observation before authorities will be able to determine whether the event has passed, Green said. Pacific island nations urge people to avoid coastlines Authorities in a number of small island nations in the South Pacific Ocean urged people to stay away from coastlines, familiarize themselves with evacuation routes and await further guidance from officials, but did not order evacuations. Some tiny and low-lying Pacific island chains are among the world's most imperiled by tsunamis and rising seas. Cautions to stay away from beaches until any wave surges passed late Wednesday were issued by officials in Fiji, Samoa, Tonga, Federated States of Micronesia and Solomon Islands. Nearly 2 million people under evacuation advisories in Japan Japan's Fire and Disaster Management Agency said nearly 2 million residents are now under evacuation advisories in more than 220 municipalities along the Pacific coast as of midday Wednesday. It added that one person was slightly injured on the northern island of Hokkaido when a woman in her 60s fell while rushing to evacuate. She was taken to a hospital. Governor says Hawaii is ready for evacuations Hawaii Gov. Josh Green said data from Midway Atoll, which is part of the way between Japan and Hawaii, measured tsunami waves from peak to trough of 6 feet (1.8 meters). He said waves hitting Hawaii could be bigger or smaller and it was too early to tell how large they would be. A tsunami of that size would be akin to a three foot (90 centimeter) wave riding on top of surf, he said. Hawaii Gov. Josh Green said data from Midway Atoll, which is part of the way between Japan and Hawaii, measured tsunami waves from peak to trough of 6 feet (1.8 meters). He said waves hitting Hawaii could be bigger or smaller and it was too early to tell how large they would be. A tsunami of that size would be akin to a three foot (90 centimeter) wave riding on top of surf, he said. He told a new conference that a wave that size could move cars and throw fences around. 'It can dislodge trees, that's why you can't just be out there. The impact is at great speed,' Green said. 'Any any structure that gets loose and strikes the individual could take them out. And people can drown quite easily with the force of that kind of wave.' Green said Black Hawk helicopters have been activated and high-water vehicles were ready to go in case authorities need to rescue people. 'But please do not put yourself in harm's way,' he said. Tsunami sirens sound in remote California city The small Northern California community of Crescent City turned on its tsunami sirens to warn residents about possible waves. 'You are hearing a Tsunami Siren. We are under a Tsunami Warning. Please stay away from beaches and waterways. A predicted wave may hit at 11:55 pm. We are waiting on additional information about any level of evacuation,' read a post from the City Hall Facebook account. The city in rural Northern California has roughly 6,000 residents. A tsunami in 1964 caused by an earthquake in Alaska caused a wave 21 feet (6.4 meters) high to hit the city, killing 11 people and destroying its downtown. Lines form at Honolulu gas stations There were long lines at gas stations near downtown Honolulu, with standstill traffic even in areas away from the shoreline. A Texaco gas station in the Nuuanu-Punchbowl neighborhood closed early so that workers could go home. The workers set out cones at pumps and turned away motorists. Jimmy Markowski, on a family vacation from Hot Springs, Arkansas, ended up at the closed Texaco station after fleeing their Waikiki beach resort in a caravan of three cars carrying 15 people. 'All we're trying to do is just figure out what we're going to do for the next three or four hours,' he said. 'We've got water, we got some snacks ... we're going to stay elevated. This is our first tsunami warning ever. So this is all new to us.'

Tsunami evacuations ordered in South America
Advertisement The dire warnings following the massive quake early Wednesday off Russia's Kamchatka peninsula evoked memories of catastrophic damage caused by tsunamis over the last quarter-century. Get Starting Point A guide through the most important stories of the morning, delivered Monday through Friday. Enter Email Sign Up In Japan, people flocked to evacuation centers, hilltop parks, and rooftops in towns on the Pacific coast with fresh memories of the 2011 earthquake and tsunami that caused a nuclear disaster. Cars jammed streets and highways in Honolulu, with traffic at a standstill even far from the sea. 'We've got water, we got some snacks ... we're going to stay elevated,' said Jimmy Markowski, whose family from Hot Springs, Arkansas, fled their Waikiki beach resort before evacuation orders were lifted. 'This is our first tsunami warning ever. So this is all new to us.' US Secretary of Homeland Security Kristi Noem said the worst was over. Later Wednesday, tsunami advisories for Hawaii, Alaska, Oregon, and Washington state were canceled, but remained for parts of northern California, where authorities warned to stay away from beaches and advised that dangerous currents should be expected through Thursday morning. Advertisement Experts say it's challenging to know when to drop advisories, which signal the potential for strong currents, dangerous waves, and flooding. 'It's kind of hard to predict because this is such an impactful event and has created so many of these waves passing by,' said Dave Snider, tsunami warning coordinator for the National Tsunami Warning Center in Alaska. The earthquake appeared to be the strongest recorded since the 9.0 magnitude earthquake off Japan in 2011 caused a massive tsunami and meltdowns at a nuclear power plant. The International Atomic Energy Agency said initial reports showed Japan's nuclear plants were not affected this time. Wednesday's quake occurred along the 'Ring of Fire,' a series of seismic faults around the Pacific Ocean. It was centered offshore, about 120 kilometers (75 miles) from Petropavlovsk-Kamchatsky, Kamchatka's regional capital. Multiple aftershocks as strong as 6.9 magnitude followed. Russia's Oceanology Institute said tsunami waves of less than 6 meters (20 feet) were recorded near populated areas of the peninsula. Lava began flowing Wednesday from the Northern Hemisphere's largest volcano in a remote area of Kamchatka, the Russian Academy of Sciences' geophysical service said. Chile, a place highly vulnerable to earthquakes and tsunamis, raised its warning to the highest level early Wednesday for most of its lengthy Pacific coast and began evacuating hundreds of people. 'Remember that the first wave is usually not the strongest,' Chilean President Gabriel Boric warned on social media. Advertisement Colombian officials ordered the complete closure and evacuation of beaches and low-tide areas while maritime traffic was being restricted. Ecuador canceled classes at schools in the Galapagos Islands as well as communities along the coast. Coastlines of New Zealand — about 6,000 miles (9,600 kilometers) from the quake's epicenter — were experiencing strong currents and wave surges. There were no evacuations, but people throughout the South Pacific island nation were warned to stay out of the water and away from beaches, shorelines, and harbors. Authorities in Hawaii downgraded the state to a tsunami advisory early Wednesday, and evacuation orders on the Big Island and Oahu, the most populated island, were lifted. 'As you return home, still stay off the beach and stay out of the water,' said James Barros, administrator of the Hawaii Emergency Management Agency. In northern California, tsunami activity continued Wednesday morning with waves of 3.6 feet (1.1 meters) in Crescent City, which has a Even waves of just several feet high might pose a significant risk. 'It might only be 3 feet, but it's a wall of water that's 3 feet and spans hundreds of miles. Three feet of water can easily inundate inland and flood a couple blocks inland from the beach,' said Diego Melgar, director of Cascadia Region Earthquake Science Center at the University of Oregon. In Petropavlovsk-Kamchatsky, the quake damaged a local kindergarten that was unoccupied. A video released by a Russian media outlet showed a team of doctors at a cancer clinic on Kamchatka holding a patient and clutching medical equipment as the quake rocked an operating room. Authorities on the Advertisement A tsunami of 2 feet (60 centimeters) was recorded in Hamanaka town in Hokkaido and Kuji port in Iwate, according to the Japan Meteorological Agency. Several areas reported smaller waves, and at least one person was injured. In Iwaki, a city in Fukushima prefecture, which was the epicenter of the 2011 tsunami and quake, dozens of residents gathered at a hilltop park after a community siren sounded and breakwater gates were closed. Workers at the Fukushima Daiichi nuclear plant, severely damaged in 2011, took shelter on higher ground while remotely monitoring operations, the operator said. Hours later, Japan downgraded its tsunami alert but left an advisory in place along the Pacific coast.
